Contrast Enhancement in Color Extended Visual Cryptography
Visual cryptography is a secret sharing technique mainly used for image sharing. In the case of extended visual cryptography we use meaningful shares to hide image. Contrast loss in decrypted image is a major problem. Here we use Additional basis matrix and perfect white pixel reconstruction to improve the contrast in color extended visual cryptography. Keywords— Visual Cryptography (VC), Halft...
متن کاملColor category influences heterogeneous visual search for color.
Many previous studies have revealed chromatic characteristics of visual search using relatively simple stimuli. They suggested that color difference between a target and distractors was a crucial factor. However, it may not be applicable to natural environments that contain numerous colors. This study demonstrates the existence of a color-category effect on heterochromatic visual search. Color ...
متن کاملVisual search at isoluminance: Evidence for enhanced color weighting in standard sub-set and preview-based visual search
Isoluminant displays depend on responses from the parvocellular visual stream, known to code color information. We examined the influence of isoluminance on attentional guidance by color using two procedures: (i) color sub-set search (Egeth, Virzi, & Garbart, 1984) and (ii) preview search (Watson & Humphreys, 1997). We used displays that do not generate a sub-set search advantage with luminant ...
متن کاملColor channels, not color appearance or color categories, guide visual search for desaturated color targets.
In this article, we report that in visual search, desaturated reddish targets are much easier to find than other desaturated targets, even when perceptual differences between targets and distractors are carefully equated. Observers searched for desaturated targets among mixtures of white and saturated distractors. Reaction times were hundreds of milliseconds faster for the most effective (reddi...
متن کاملGlaucomatous visual field damage. Luminance and color-contrast sensitivities.
Using a modified Humphrey perimeter, we evaluated 16 eyes with primary open-angle glaucoma and visual field loss (defects 0.5-3.0 log units in depth), and 14 normal eyes. Each eye was tested twice in random order with conventional luminance-increment static perimetry and with the perimeter modified to produce a high-luminance yellow adapting background and a blue test stimulus. The background w...
